Overview

When using a Desktop Environment or Window Manager that doesn't allow for the settings of QT themes, you can set QT to use your GTK themes instead.

Using qt5ct

Note

In some Manjaro editions, this is already done for you by default

Install qt5ct using your favorite package manager or the command:

pamac install qt5ct

Set environment variables in ~/.profile by adding or updating the following lines:

export QT_QPA_PLATFORMTHEME="qt5ct"

Run the application QT5 Configuration Manager from the menu or run the command qt5ct.

-=Introduction=
-For those of us that use [https://en.wikipedia.org/wiki/GTK%2B#Desktop_environments Desktop Environments] &/or [https://en.wikipedia.org/wiki/GTK%2B#Window_managers Window Managers] that use GTK+ , this fix is particularly helpful.
+=Overview=
-For those such as myself that run 1080p or higher screen resolutions on largish monitors it can be quite a strain on the eyes when you can't control the size of the fonts that an application uses.
+When using a [[Desktop_Environments|Desktop Environment]] or Window Manager that doesn't allow for the settings of QT themes, you can set QT to use your GTK themes instead.
-This fix makes your Qt app's use your GTK+ theme (colours & such) & your chosen font settings.

+{{note|In some Manjaro editions, this is already done for you by default}}
-) Install '''qt5ct'''
-) Set environment variables in '''/etc/profile''' and add the following lines:
+Install {{ic|qt5ct}} using your favorite package manager or the command:
+ pamac install qt5ct
-'''export QT_QPA_PLATFORMTHEME="qt5ct"'''
-'''export QT_AUTO_SCREEN_SCALE_FACTOR=0'''
+Set environment variables in {{ic|~/.profile}} by adding or updating the following lines:
+ export QT_QPA_PLATFORMTHEME="qt5ct"
-) source the file by using: <code>source /etc/profile</code>
-) Start '''qt5ct'''
+Run the application '''QT5 Configuration Manager''' from the menu or run the command {{ic|qt5ct}}.
-) In the first tab '''Appearance''' choose '''Standard Dialogs: default''' (some people get crashes if they choose GTK3)
-Because we used /etc/profile to set the environment variables back in step 2), after you reboot, both the user & root accounts will be able to benefit from these changes.
